Clear and powerful sound (I don't know much about sound range). The speakers can be heard clearly even with movement on the street. However, I can also hear external noises as they are not completely blocked and shift while walking.

The negatives are that they cause itching and sweating, and they never sit properly for a long time. They come off the pillow and press the buttons if you want to sleep with relaxing music. So, 3/5 for those who want them for running and sleeping.

I rate them generously with 4/5 as I use them minimally and it's only been a month, and I will revisit for a thorough evaluation over time.

Amazing battery, that's why I chose them from the beginning, they last 6-7 hours without putting them in the case. With the case, you forget to charge them, in general, anything Anker I have bought regarding batteries is top-notch. Sound quality is very satisfying for their price (29.90). Decent microphone, the only problem I have is that their design doesn't fit well in my ear and they often fall out during workouts. It may be different for everyone, of course. Besides that, it's a great purchase for their price!
